How can I delete Word from my Mac if it says permission denied?

First, check that you're deleting the actual app from the Applications folder, not just an icon in the Dock. Quit Word, then try moving Microsoft Word from Applications to the Trash.

If you still get permission denied, select the app in Finder and open Get Info. Check Sharing & Permissions and whether the app is locked. An administrator account may be needed to change permissions or remove it.

Is the item actually in Applications, or is it a file stored in iCloud Drive? Those are different things. If it's an iCloud file rather than the installed app, you can try deleting it from iCloud Drive or through iCloud.com.

If this is a work or school Mac, the app may be managed by your organization. In that case, permission changes might not be available to you, so check with whoever manages the Mac rather than forcing the deletion.
